Population Growth and Economic Development

how does the rate of population growth affect economic growth

Although its economy is very successful, many workers and civilians are dying. The figure illustrates the extent to which the classic Malthusian channel operates only over relatively long time horizons. This research explores the effect of population growth on the economic growth of Nigeria over the period of 1981 to 2015. The final question is how this extra disposable income will be divided between saving and consumption. The Malthusian Trap and the Demographic Transition In 1798, Thomas Robert Malthus published his Essay on the Principle of Population. They start by making alternative population forecasts for India under three exogenous fertility scenarios: high constant at its 1951 level , medium declining 50 percent over the period 1966—1981 , and low declining 50 percent over the period 1956—1981.

In this paper, we attempt to quantify the first eight of these effects Malthus, Solow, dependency, life-cycle saving, experience, life-cycle labor supply, childcare, and child quality. These results are undoubtedly influenced by the exceptional economic performance in China and other large emerging economies although economic growth also picked up in many low-income countries.

Population Growth and Economic Development

how does the rate of population growth affect economic growth

In contrast to much of the literature up to the time, there is a strong emphasis on the role of human capital, and the increase in the fraction of national income that must be devoted to education when fertility is high. This procedure is explained in Section 4. Returns to investment in education: A global update. In these regressions, terms representing population growth, labor force growth, or dependency ratios are included as right hand side variables. The figure shows that schooling plays an appreciable role in determining the economic effects from reduced fertility. Output is produced in a neoclassical production function that takes physical capital, land, and a human capital aggregate embodying education and experience as inputs.

The Effect of Fertility Reduction on Economic Growth

how does the rate of population growth affect economic growth

We think that a key advantage of the simulation model we have presented is its transparency. Mankiw, Macroeconomics, fourth edition, chapter 5, problems and applications 4. It will be seen from this table that the annual growth in per capita income has been much less than the annual growth rate in that national income. While the Chinese government has denied that forced abortions and sterilizations are part of its strategy, policies are administered locally, and all of the above means of coercion seem to have been employed at one time or another.

These could include human capital, health, characteristics of institutions, cultural outlook, and so on. But such a method of adjustment is not easy to achieve in India. An additional advantage of our methodological approach is that we are able to look not only at the aggregate effect of fertility reduction on income, but also at the different channels through which this effect operates. For Malthus, the long-run fate of human beings was a standard of living barely sufficient to keep them alive. The fact that changes in economic outcomes are sometimes regressed on lagged changes in fertility as represented, for example, by population age structure is only a slight improvement, since there is bound to be serial correlation in the unobserved factors that affect both fertility and economic outcomes. Average annual world population growth over this period was about 1% but has varied considerably across regions and over time. We then do a full decomposition, showing the relative importance of the different channels at different time horizons.

how does the rate of population growth affect economic growth

In: Schmidt-Hebbel Klaus, Servén Luis. More specifically, their regression explains approximately 20 percent of the growth of income per capita on average over the period 1960—1995. Thus, for the first 15 years of the simulation this channel contributes little to higher income. The effect of the land-labor ratio on income per capita We conduct a similar exercise to look at the importance of the capital-shallowing channel. Low savings per capita are associated with young population and high fertility. It can just refer to any growth in the value of an economy as a whole. Apart from this, political factors, such as participation of government in formulating and implementing various policies, have a major part in economic growth.

Answers

how does the rate of population growth affect economic growth

An increase in any of these factors will cause an increase in the potential output of an economy meaning it has the potential to produce more. As with the Malthus effect, for the first 15 years of the simulation, suppressing the Solow effect makes no difference to the level of income per capita because the number of workers does not differ between the baseline and alternative scenarios. For an issue that has been studied for so long, and with such potential import, the base of evidence regarding the economic effects of fertility or population growth more generally is rather weak. Second, new research suggested that there was in fact a negative association between population growth and economic performance. But the standard of living is yet to achieve any appreciable improvement.

In Section 6, we consider two alternative models of investment. He finds that ability to postpone first births leads to higher education as well as independence for women. The channel turns out to be rather weak. The Board of Governors of the Federal Reserve System; 1996. Institute for the Study of Labor; 2006.

Following the analyses of , , and most of the simulation models discussed above, we focus on the effects of slowing population growth due to an exogenous decline in fertility. Much of our emphasis is on the channel of human capital, which was also emphasized by. As a result, the estimates recorded in the data sets may be somewhat less reliable than would be the case for more recent statistics. With an open economy, the capital stock initially rises somewhat faster in response to lower fertility in the alternative scenario relative to baseline because of the increase in labor supply from reduced childcare, as well as the increase in human capital from schooling as school-age cohorts at the time of the fertility decline start joining the labor force, both of which produce a nascent rise in the marginal product of capital. Public opinion is strongly opposed to it. It turns out that economists have developed theoretical arguments supporting both the idea that population growth slows growth in per capita output and the opposite idea that population growth stimulates greater economic growth. In addition to raising income directly by lowering the dependency ratio, the capital accumulation from this extra saving can result in an increase in output per worker.

Demographic transitions and economic miracles in emerging Asia. This will lead to cascading events that will negatively impact the marine environments and the quality of water. We assess quantitatively the effect of exogenous reductions in fertility on output per capita. This yields an income growth differential between the two scenarios of 0. We construct a general equilibrium model in which fertility and mortality and thus population size and age structure are exogenous.
